Circuit/System Description
The BCM receives a discrete input from 2 ajar switches to indicate the status of the liftgate. The liftgate ajar switches are normally open when the liftgate is fully closed. When the liftgate is opened, the ajar switch contacts close providing a path to ground. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the liftgate ajar status and the driver information center (DIC) located at the bottom of the IPC, illuminates the rear access open message.
